Saint John is the only city on the Bay of Fundy, hence it’s sometimes referred to as “Fundy City”. It’s known for the Reversing Rapids, a phenomenon caused by bay tides colliding with the Saint John River and for having the highest tides in the world. Twice a day, the bay fills and empties close to a billion tonnes of water! You can enjoy all of the natural wonders, including participating in whale watching, kayaking, hiking, bird watching, and even golfing.
